Accuracy, validity, and reliability are the primary objectives of any scientific discipline. K9 detection work shares these primary objectives--also across all disciplines. In the realm of detection dog science, scientists sometimes need to learn from handlers because the laboratory and the field are radically different settings. The pursuit of the science behind how K9 teams work and why they can be so effective is critical to legitimizing their credibility as biosensors. "Dog detector teams support law enforcement and first responders in a variety of tasks, ranging from drug and contraband interdiction to locating human remains; however, the lack of peer-reviewed research and recent media coverage of dog detection failures has raised concerns about the effectiveness of dog-based detection and its admissibility in court" (Forensic Technology Center of Excellence, 2018).
